HEATING AND COOLING APPARATUS.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed. September 19, 1917. Serial No. 192,113.

T 0 all whom it may concern:

Be it known that I, NIELS D; NIELSEN, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements'in Heating and Cooling Apparatus; and I do hereby de'clarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same;

.My invention relates to improvements in apparatus for sprinkling tanks or vats with a fluid for affecting thecontents of the vats, such as by changing the temperature thereof.

One of-the objects of my invention is to provide means which will distribute the fluid sprinkled against the tanks uniformly over the surface thereof, and which can, at the same time, be conveniently cleaned or removed for cleaning or other, purpose.

I also aim to provide means which is simple' in construction, easy to assemble, convenient to use and highly efficient.

Other objectsof my invention and the invention-itself will be understood from a description of the invention. v V

Figure '11s a section of an assembly view of an embodiment of my invention taken on the line A--A of Fig. 2. .v Fig. 2 is a top plan View of the apparatus illustrated in the em- 7 bodiment shown in F ig. 1. assembled. Fig.

3 is an enlarged detail section of the left hand pipe and related parts shown in F i 1. Fig. 4 is a section taken on line B of Fig. 3. Fig. 5 is a plan view of the clamping collar and related parts.

Referring now tothe drawing and to the embodiment of the invention shown therein, at 5.1 have illustrated a tank or vat comprising side walls (Sand a bottom 7. I have to the walls of thetank'and jacket.

here shown a cylindrical tank with a Hat apronis provided with a plurality of openings 12, which may be of any Suitablenum- The her. In the embodiment shown four have been employed. These openings are shown adjacent the side walls 9 of the jacket.

Supporting means for the sprinkling ,members are shown at 13 and here consist of stud pipes supported by the jacket, preferably by the apron 11 and the side wall 9,

in such position that the bore 14: of the pipe registers with the opening 12. In the embodiment shown, the upper end of the pipe 13 is threaded, as shown at 15 and a flange 16 is threaded thereon. The flange 16 is provided with perforations 17 for bolts 18, which clamp together the flange 16, a heat insulating medium 19 and a collar 20. The collar 20 is provided with a threaded opening 21, into which the sprinkling member 22 is secured. In theembodiment shown, the sprinkling element consistsof a tube22 closed at the free end 23, and which extends substantially parallel to the side wall of the tank. In the e1nbodiment shown theside wall of the tank being straight, the tube 22 is straight. The tube 22 is provided with a. plurality of groups of openings, one of which is shown at 25 in Fig. 4 and consists of three openings 26, 26 and 26", so directed as to cause the liquid to be distributed in different directions, so as to engage different parts of the walls of the tank. It is obvious that these groups may contain any suitable number of openings and that they may be directed in any suit able manner., I

The upper part of the tube is threadechas shown at 27 and as explained, screwed into the opening 21 in the collar 20, so that both the tube and the collar may be removed by removing the bolts 18. A feed pi e is shown at 30 and in the embodiment siown extends all around the tank. This pipe is preferably made in sections, as shown at 31, 31, 31 and 31 in Fig. 2. These sections are connected together in any suitable manner, as by flanges and fastening means, illustrated at 32.

Valves are shown at 33 for controlling the liquid fed from the pipe 30 to the sprinkling members. A supply pipe is illustrated at 34 for supplying liquid to the feed pipe. I When it is desired to clean the sprinkling member,

the same may be entirely removed by removr i prov ded w th an opening into whlch a tube reads, means to removably 11 fasten said ing the'bolts 18 and disconnecting the section of the feed pipe devoted to the particular sprinkling member to be removed, or the tube may be cleaned bydisconnecting the valve 33 and the section of the feed 'pipede I rvoted to the particular tube to be cleaned by unscrewing the valve from the top of the tube' It will be apparent that the valves need not be all opened at the same time. It may be advisable'during certain times, for in- V stance, over night, to have only one, or posslbly two p pes del vering heating or cool- 11 Thus, I
